Grain/seed cleaning

The function of a rotary grain pre-cleaner is to remove fine and large impurities which are found among untreated grain in a short amount of time. The pre-cleaner must be installed at the entrance of the dryer so as not to compromise the quality of the grain. This particular treatment is done to homogenize the product, eliminating blockages whilst reducing the consumption of electricity. The aspirated version reduces the emission of dust into the...

The main function of a cleaner with aspiration is to remove light dust particles as the product enters the system and then separate the good quality product from the damaged and other impurities through the rotary drum. This process is essential for cleaning grain which is to be stored for long periods as it prevents overheating due to chaff, husks or split/damaged product. Once the treatment is completed the product will be visibly healthier and in...

The function of the rotary grader is to separate grain according to their size. The output capacity depends on the drum diameter and the number of perforated screens. The accuracy of grading depends on the rotation speed and inclination of the drum.

The aspirator is designed to remove light impurities from grain. It can be installed at any point in the system or as a part of any machine. It is indispensable in the grain cleaning process. It is quick and easy to install.

This pre-cleaner with aspirator is designed to remove dust and light impurities from the grain. It can be installed on processing machines only for the removal of dust or light particles. It is essential for cleaning grain. It is quick and easy to install.

The main function of this cleaner is to remove the light dust. It is equipped with a winnow aspiration system and a decanter. It can be installed on processing machines for cleaning the product of dust or light impurities. Optionally, a magnetic separation system for the removal of metallic particles can also be installed on the input nozzle. It is essential for cleaning grain.

This cleaner with aspirator removes light particles and straw present in the product. The machine is installed after the dryer or where there is product to be cleaned of only dust or light impurities. It is essential for cleaning grain that has to be stored as it reduces the risk of overheating, which can be caused by chaff, husks, split grains etc.

This aspiration cleaner removes the light particles, straw and larger impurities present in the product in a short amount of time. The machine can be installed before, after or in the receiving area of a dryer. It is a necessity in the cleaning process. When installed before a dryer it removes impurities that could cause clogging; when installed after it reduces the amount of dust among the product to be stored, which reduces the risk of overheating...

This cleaner has been designed to quckly remove both fine and large impurities that can be found among the product. It can be installed as a fixed unit or also as a mobile unit (see Combi Mobile) and is used prior to storage or transportation.

This machine has been designed to remove in a short amount of time both fine and large impurities that can be found in grain. It is installed on an easily transportable trailer (40km/h street version and 10km/h for internal use) and is used before storing or shipping the product.

Two phase cleaning system.
The product with impurities enters by way of gravity. The counterweight system allows uniform distribution of the product which encounters a cross air flow to removes lighter particles. It then enters the sieve case which contains the perforated screens installed to suit the particular treatment. The upper sieve divides the product from large impurities, the lower sieve divides the desired product from fine impurities. The...

Grain Drying

The drying column of the Energy saving grain dryer is formed by a loading hopper and a number of modules with internal conical ducts which are immersed in the grain. These descend by way of gravity in a zigzag movement.

The drying column of the Heat recovery continuous grain dryer is formed by a loading hopper and a number of modules with internal conical ducts immersed in the grain, which descends by gravitational by way of gravity in a zigzag movement. The grain is hit by a counter current of hot air in the upper part and a flow of air from the outside environment in the lower part (cooling). This then exits, a part of which is released back into the atmosphere and...

The drying column of the traditional grain dryer is formed by a loading hopper and a number of modules with internal conical ducts immersed in the grain, which descends by way of gravity in a zigzag movement. The grain is hit by a counter current of hot air in the upper part and a flow of air from the outside environment in the lower part (cooling). Part of this is then released into the atmosphere and the rest is recycled. The quantity of grain released...

The drying column of the grain dryer equipped with loading/unloading elevators is formed by a loading hopper and a number of modules with internal conical ducts immersed in the grain, which descends by way of gravity in a zigzag movement. The grain is hit by a counter current of hot air in the upper part and a flow of air from the outside environment in the lower part (cooling), which is released into the atmosphere. The quantity of grain released is...

The drying column of the dryer for raw rice is formed by a high capacity recovery hopper and by a number of modules with internal conical ducts immersed in the rice, which descends by way of gravity in a zigzag movement. The rice encounters a counter current of hot air in the lower zone, which is then released into the atmosphere. The quantity of grain released is pre-determined and regulated by a pneumatic extractor. The product is then collected in a...

OPERATION
The drying column of the small grain dryer is formed by air ducts immersed in the grain. The grain descends by way of gravity in a zig-zag pattern and encounters a cross air flow. The quantity discharged is regulated by a motorized electric extractor. The product is colected in a hopper and descends into a vertical auger (bucket elevator optional), which lifts the product and re-feeds the drying column. This cycle continues until the desired...

Zanin F.lli has been designing and building coolers for all types of dryers for over 30 years. The procedure, which increases the production of the dryer and reduces energy consumption, relies on the exploitation of the energy contained in the corn. This energy is in the form of substantial heat and the process allows for the removal of two to three points of humidity through tempering.
Slow cooling is applied essentially only to corn, even though it is...
